AUTOMATIC GRATER.

SPECIFICATION forming part of Letters Patent No. 650,303, dated May 22, 1900.

Application filed August 2, 1899. 1

T0 ctZZ whom it may concern.-

Be it known that I, EMMANUEL CRUPE, a citizen of the United States, residing at San Francisco, in the county. of San Francisco and State of California, have invented certain new and useful Improvements in Automatic Graters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates generally to that class of devices known in the art as culinary utensilsg but, to be more specific, the device is a grater arranged to act in conjunction with an automatic feed.

Besides possessing the strength and durability requisite in such devices my invention is so constructed that the article to be grated can be quickly placed in the required position relative to the gratingsurface and subsequently a compact housing thrown up to form a complete inclosing medium for the operative parts. The feeding is absolutely automatic, thereby obviating any danger of injury to the operators fingers, which is very apt to occur where the article is fed in the usual manner.

The ability of the various parts of my invention of being unfolded and separated is worthy of especial mention, as it affords ample opportunity to thoroughly cleanse the device after each operation, and thereby remove all foreign matter apt to destroy the natural flavor of the substance subsequently operated upon.

In carrying out the above main ideas I have not overlooked the matter of simplicity and economy of construction.

Other objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the accompanying drawings, in which similar letters and numbers of reference designate corresponding parts, Figure 1 is a perspective view of the device, showing the main operative parts by means of dotted lines. Fig. 2 is a central vertical section, and Fig. 3 is a section taken in a direction at right angles to Fig. 2.

Referring now to the above Views, numeral Serial No. 725,922. (No model.)

down into a plane coincident with the plane of the base 2. Longitudinally journaled in opposite sides of the box is the shaft 4, upon which is rigidly mounted the cylindrical grating-surface 5. One end of this shaft protrudes beyond the box 1 and is provided with a crank 6. Inclosing the cylinder 5 and provided with a semicircular top is the feeder 7, which is formed of ribbed wire or other suitable material aud of two halves hinged to gether at the point 8. This feeder isguided for vertical motion in the box 1 by means of the guides 9, whose extremities are held in place by being turned at right angles and entering the opposite walls of the box in the manner shown in Fig. 2.

In order to cause the upper extremity of the feeder 7 to press against the cylinder 5,

I have provided the coiled springs 10, which. encircle guides 9 and are attached to the lower extremity of the feeder.

It will be readily seen that as the front a is thrown open and the forward half of the feeder 7 thrown up the article to be grated can be readily interposed between the semicircular extremity of the feeder and the upper surface of the cylinder 5. Now as the parts are closed into their normal position and the crank 6 turned the springs 10 will force the article against the revolving grater and grind it into the form desired. After the gratings leave this revolving cylinder they fall by gravity into the lower sliding drawer 11, from which they can be readily removed when desired. It is further manifest that by unscrewing the crank 6 from the shaft 4 the walls of the box can be easily unfolded and the entire interior mechanism readily removed for purposes for cleansing.

From the above description it will be seen that I have provided a very simple, compact,

and effective grater and one having a perfectly-automatic feeder.

I am perfectly aware thatchanges in the form and proportion of parts of the devices herein shown and described as an embodiment of my invention, as well as the material of which they are composed, can be made without departing from the spirit or sacrificing the advantages thereof, and Itherefore reserve the right to make such changes, substitutions, and alterations as fairly fall within the scope of my invention.

I What I claim, and desire to secure by Letters Patent, is- 1 1. In a device of the class described, the

combination with a removable rotary grater, a feeder inclosing said grater, and a plurality of springs on opposite sides of said graterand adapted to pull said feeder toward said-grater,

said feeder being formed with a hinged poition through which the article to be grated is inserted, and a housing without said feeder,

' said 'r'otary grater being journaled in said housing, substantially as and for the purpose set forth.

' 2. A grater consisting of a roughened ro- "tary surface, a feeder extending beyond andinclosin g said grater, said feederfbei-n g formed with ahinged portion, a casing inclosingsaid hinged portion, opposite ends of said shaft protruding through slots in said feeder and journaledin said casing, one or more springs at each end of said feeder and attached to said feeder and to said casing, and operating to urge said feeder toward said grater, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses;
